黏滞力是流体受到剪应力变形或拉伸应力时所产生的阻力。在日常生活方面,黏滞像是“黏稠度”或“流体内的摩擦力”。因此,水是“稀薄”的,具有较低的黏滞力,而蜂蜜是“浓稠”的,具有较高的黏滞力。简单地说,黏滞力越低(黏滞系数低)的流体,流动性越佳。
还给出了垂直湍流黏滞系数呈抛物型的分布特征。
The vertical turbulent coefficients were found to display a parabolic structure.
含油泥岩黏滞系数较小,显示出其流动变形大的特点。
The creep viscosity coefficient is become much smaller, which reveals the characteristics of large creep deformation.
